Texas Instruments TPS650001EVM-585

Overview

TPS650001EVM-585 from Texas Instruments is an evaluation module designed to demonstrate the TPS650001RTE power management IC-a single-chip solution integrating a 2.25 MHz step-down converter (1.2 V, 600 mA) and dual low-dropout regulators (1.8 V and 2.8 V, each 300 mA). It supports flexible input sourcing (2.3–6.0 V), PFM/PWM mode selection, and power-good sequencing for portable embedded systems.

For engineers reviewing the TPS650001EVM-585 datasheet, TPS650001EVM-585 pinout, TPS650001EVM-585 application, or TPS650001EVM-585 equivalent, this board enables rapid validation of DC/DC efficiency, LDO transient response, startup timing, and multi-rail sequencing in battery-powered point-of-load designs.

Technical Context

The TPS650001EVM-585 implements the TPS650001RTE IC in a production-ready 2-layer PCB layout (50.8 mm × 61.09 mm), with accessible test points and jumper-configurable enable/control signals (JP1–JP6) for independent DCDC and LDO activation, input source selection (VIN or VODCDC), and MODE (PWM/PSM) control.

It provides direct measurement access to all critical rails-VODCDC (J2), VLDO1 (J3), VLDO2 (J4), and PG (J5)-with twisted-pair input connections (J1) and integrated 2.2 µH power inductor (LPS3015-222ML), enabling accurate efficiency, ripple, and load/line transient characterization per SLVU357 performance curves.

FAQ

What is the primary function of the TPS650001EVM-585?

The TPS650001EVM-585 is an evaluation module-not an IC-that demonstrates the operation of the TPS650001RTE power management IC. It provides physical access to all input/output rails, enable controls, and monitoring signals (including PG) to validate voltage regulation, efficiency, transient response, and sequencing behavior under real-world conditions.

Does the TPS650001EVM-585 include the TPS650001RTE IC?

Yes, the TPS650001EVM-585 integrates one TPS650001RTE IC (QFN-16 package) as its core device. This IC delivers a 1.2 V/600 mA step-down converter and dual LDOs (1.8 V and 2.8 V, each 300 mA), fully configured per the SLVU357 User's Guide schematic and bill of materials.

Can the TPS650001EVM-585 be used to evaluate other variants like TPS650003 or TPS650006?

No-the TPS650001EVM-585 is configured exclusively for the TPS650001RTE variant, with fixed output voltages (1.2 V / 1.8 V / 2.8 V). While the same EVM platform supports those variants via component-level changes (per Table 1 and BoM notes), the shipped TPS650001EVM-585 unit contains only the TPS650001RTE IC and associated default resistor/capacitor values.

How is power sequencing controlled on the TPS650001EVM-585?

Sequencing is implemented via independent jumpers: JP1 enables/disables the DCDC converter; JP2 and JP3 control LDO1 and LDO2 separately; JP4 selects PWM or PSM mode; and J5 provides the combined PG signal that asserts only when all three regulated outputs are within 90% of their nominal values and all enables are active.

What input voltage range is supported by the TPS650001EVM-585?

The TPS650001EVM-585 accepts 3.3 V to 6.0 V DC input via J1 (VIN/GND), as specified in Section 4.7 of SLVU357. This range aligns with the TPS650001RTE's 2.3–6.0 V input rating and ensures stable operation across typical Li-ion and multi-cell battery configurations used in portable devices.
